Research : Mechanisms of biological tube formation in Drosophila tracheal system

Biological tube formation is a developmental process required for the formation of the respiratory, vascular and glandular systems of the body. Defects in tube formation result in numerous human diseases including polycystic kidney disease, atherosclerotic heart disease and cancer. The Drosophila trachea system is a complex interconnected tubular network that delivers oxygen to every cell of the body. It is an excellent model system to study the molecular basis of cell migration, cell recognition, cell adhesion and branch fusion during tube formation. Dr. Jiang's work is focused on studying the regulation of tracheal gene expression and how tracheal-expressed genes control the complex cellular behaviors that result in the formation of a continuous tubular network. Current projects in her lab focus on 1) using molecular biology techniques to determine minimal regulatory regions of tracheal-expressed genes to identify potential direct regulators, 2) using expression profiling and cell-separation techniques to isolate tracheal cells and examine gene expression changes at different developmental time-points. 3) using genetics to understand the role that tracheal genes play during the development and function of the tracheal system.
